All Implemented Interfaces:

```
public final class DsfPosition
extends Object
implements SecuritizedProductPosition<Dsf>, Resolvable<ResolvedDsfTrade>, org.joda.beans.ImmutableBean, Serializable
```
A position in a DSF.
A position in an underlying Dsf.
The net quantity of the position is stored using two fields - longQuantity and shortQuantity. These two fields must not be negative. In many cases, only a long quantity or short quantity will be present with the other set to zero. However it is also possible for both to be non-zero, allowing long and short positions to be treated separately. The net quantity is available via getQuantity().
Price
Strata uses decimal prices for DSFs in the trade model, pricers and market data. The decimal price is based on the decimal multiplier equivalent to the implied percentage. Thus the market price of 100.182 is represented in Strata by 1.00182.

```
    Obtains an instance from position information, product and net quantity.
    The net quantity is the long quantity minus the short quantity, which may be negative. If the quantity is positive it is treated as a long quantity. Otherwise it is treated as a short quantity.
    
    Parameters:
    
    positionInfo - the position information
    
    product - the underlying product
    
    netQuantity - the net quantity of the underlying security
    
    Returns:
    
    the position
  - ofLongShort
